As shown in Fig. 5 Yu Figure 10, described automatic sealing parts 6 include driving cylinder 61, hush panel 62, drive cylinder 61
Cylinder body is installed on the housing of centrifugal exhaust fan, drives the piston rod of cylinder 61 be installed in hush panel 62 and drive hush panel 62
Folding is on air outlet 51.The sidewall of described vacuum chamber 32 is provided with two grades of wear-resisting slanting baffles 36, and two grades of wear-resisting slanting baffles 36 are fitted
Join and be installed on dust and enter the moving towards path of vacuum chamber 32 from two grades of suction ports 33.
It addition, 24, two grades, described one-level coarse filtration dust mouth dust-exhausting port 34 is respectively equipped with the soft set of folding 10.
Referring to figs. 1 through shown in Figure 12, a kind of down-the-hole drill using above-mentioned two-stage dry dust removal apparatus, it includes frame
15, assembly 17, drill bit assembly 18, crossbeam 19 and two-stage dry dust removal apparatus are controlled.Described drill bit assembly 18 is slidably connected to
On crossbeam 19, equipped with the promotion oil cylinder promoting drill bit assembly 18 to slide on crossbeam 19.Further, drill bit assembly 18, two-stage dry type are removed
Dirt device is connected with control assembly 17 respectively.Wherein, described control assembly 17 controls the centrifugal convulsion of two-stage dry dust removal apparatus
Machine 5 cut-offs, and external compressed air is connected with the air accumulator 71 of two-stage dry dust removal apparatus by high pressure mozzle 161.
I.e., as shown in Figures 1 to 12, the operation principle of the present invention is:
When down-the-hole drill runs, assembly 17 controls drill bit assembly 18, centrifugal exhaust fan 5 is opened in control.External compressed air is to brill
Head assembly 18 conveying high-pressure source of the gas, orders about drill bit assembly 18 and carries out down-the-hole boring, and period can produce substantial amounts of rock dust.This
Time, due to centrifugal exhaust fan 5 swabbing action, promote rock dust to be sucked by dust suction cover body 11 and enter one-level through mozzle 4 and remove
In the dust-collecting cavity 22 of dirt parts 2.Owing to the sectional area of one-level coarse filtration staving 21 is much larger than dust collecting opening sectional area, entrance one-level is made to remove
The air velocity containing dust of the dust-collecting cavity 22 of dirt parts 2 reduces rapidly.And, the rock dust collision wear-resisting slanting baffle of one-level
Form eddy current at dust-collecting cavity 22 after 26, it is to avoid rock dust directly clashes on one-level coarse filtration staving 21, reduce noise, protect one-level
Coarse filtration staving 21.Meanwhile, the dust granules of suction preferably can be separated with air stream, make gravel because of gravity along dust-collecting cavity
The wall of 22 backs down the soft set of folding toward one-level coarse filtration dust mouth 24 under gravity when the dust assembled reaches constant weight
10 and landing ground, and the thinnest dust of part can flow along air-flow to one-level fine straining targeting port 25, thus lead to two grades and remove
On dirt parts 3.
When dust enters two-stage dust removal parts 3, under the effect of centrifugal exhaust fan 5, make dust concentrate and suck vacuum chamber
32.Heavier oarse-grained rock dust, after two grades of wear-resisting slanting baffles 36 stop, makes flow direction change into oblique lower section.?
Under action of gravity, make heavier oarse-grained rock dust settling and be gathered on two grades of dust-exhausting ports 34, when the dust assembled reaches
To backing down the soft set of folding 10 during constant weight under gravity and same landing ground.
Period, lighter dust can be along with distinguished and admirable being adsorbed on filtration core 35 of centrifugal exhaust fan 5 drive.
In the middle of down-the-hole drill break-off gap, connect control circuit due to pressure switch 73 decompression, make driving cylinder
61 commutations.The hush panel 62 utilizing automatic sealing parts 6 closes air outlet 51, makes vacuum chamber 32 be formed and seals cavity, two grades of suctions
The dirt casing 31 gas containing dust stops flowing.Immediately, start automated cleaning control parts 7. utilize pulse control instrument 76 to
If two normally closed solenoid valves 74 send the unlatching signal of telecommunication of scheduled duration successively, connect high-pressure air source, make high pressure air warp
Divided conduit 72 by air accumulator 71, normally closed solenoid valve 74, air-flow, quickly spray to filtration core 35 inner chamber from the fumarole 8 of injection tube 39
Gas, it is achieved automatically remove absorption dust on filtration core 35 outer surface.When automatic dust-cleaning EP (end of program), rig recover boring and make
During industry, owing to pressure switch 73 obtains pressure signal and half closed circuit, make driving cylinder 61 automatic reverse and open air outlet 51,
The two-stage dry dust removal apparatus of this product automatically restores to normal dust removal state.So, make containing this two-stage dry dust removal apparatus
Down-the-hole drill easy to operate, reduce cost, and pick-up performance can be strengthened, protection working environment and health of human body, can reduce again
The infringement of air exhauster, it is ensured that it uses quality.
It addition, down-the-hole drill run duration, dust-collecting cavity 22, vacuum chamber 32 are respectively at negative pressure state, so that folding is soft
Set 10 is in 24, two grades, one-level coarse filtration dust mouth of closedown dust-exhausting port 34.When being in 24, two grades, one-level coarse filtration dust mouth dust-exhausting port 34
On rock dust soft for folding set 10 can be backed down when having enough weight, make dust respectively from dust-collecting cavity 22, vacuum chamber 32 voluntarily
Draw off outward.When down-the-hole drill is out of service, the soft set of folding 10 can affranchise state, makes dust-collecting cavity 22, vacuum chamber 32 remain
Dust concentrate discharge, strengthen dust removing effects.
